My first class in Class CSC 119 was on 6 Jan. 2009Our lecturer was not Pn. Zuriati as we had been told but En. ABDUL MALIK MOHD RICK..He will be teaching us this subject till the end of this semester.

In this first class we had an introduction session with him.Then, we start learning the first chapter which we learn about information system that consist of 5 part that are; people, procedures, software, hardware, and data. We also learned about 3 kinds of system software programs also basic and specialized applications software. Besides that, we know about hardware that computers have 4 types which are supercomputer, mainframe, minicomputer, and microcomputer. All of us also learned about data, computer connectivity, the wireless revolution, and the Internet.

After that, En. Malik gave us 2 assignment that we had to creat our own blog and to do research on the evolution of computers and the history of Internet.

On 8 Jan 2009, we had a class. This time we learned about binary and decimal numbers which is been used in computer programming. We used our MAth knowledge this time and we learned how to convert binary numbers to decimal numbers and the other way around.

Today, on 12 Jan we gonna have a class but only for an hour. On our next class, we started learned chapter 2. It’s about THE INTERNET, THE WEB AND ELECTRONIC COMMERCE. I’ve learned about the history and creation of the Internet and the web. The internet was launched in 1969 with ARPANET and consists of the actual physical network made of wires, cables, and satellites. The web was introduced in 1992 at CERN and web provides a multimedia interface to internet resources. It has many uses but there are several most common uses which are for communicating, shopping, searching, entertainment and education or e-learning.We learned about how we actually get access to the Internet from our computer. There are internet service providers that connected to the Internet and the most widely used ISPs are national and wireless. Connection technologies include dial-up, DSL, cable, and wireless modems. Instead of that, browsers use to access the Web allowing you to surf or explore. to get access to the web we must have URLs that are locations or addresses to web resources ; 2 parts are protocol and domain name; top level domain (TLD) identifies type of organization. HTML is a command to display Web pages; hyperlinks (links) are connection. Also there is Applet which is a special program linked to Web pages; typically written in Java. Communication is some example that we can use with the Internet. E-mail (electronic mail) is the transmission of electronic messages. Basic elements: header, messages, and signature line. One thing about e-mail is sometimes it is attached to spam that is unwanted and unsolicited e-mail that may include a computer virus. But there are spam blockers, programs that identify and eliminate spam.Instant Messaging (IM) is also an example of communication that we use today. IM extends e-mail to support live communication with friends. Universal instant messagers support communication with other services.One of the fastest-growing uses of the Internet is social networking. There are 3 basic categories of social networking sites; Reuniting (e.g.: Classmate Online & Face book), Friend-of-a-friend (e.g.: Friendster & Myspace), and Common interest (e.g.: Flickr, Linkedln, and Meetup).

Search tools are one of the main parts while using the Internet. This search services operate Web sites that can locate the information we need and maintain huge databases relating to Web sites content. Spiders are programs that update these databases.We use search engines to locate information on the Web and there are 2 ways to use it which are using keyword search and directory search. Examples of search engines are Yahoo! and Google. Metasearch engines submit several search engines simultaneously and examples of metasearch engines are Dogpile, Ixquick and Metacrawler.Specialized Search Engines focus on subject specific Web sites also about the content evaluation that we should consider the following criteria to evaluate the accuracy of information on the Web: authority, accuracy, objectivity and currency.

Electronic commerce also known as e-commerce is the buying and selling of things and goods over the Internet. There are 3 basic types of electronic commerce; Business-to- consumer (B2C) and it is most widely use in online banking, online stock trading and online shopping. The second one is consumer-to-consumer (C2C) that only involves individuals selling to individuals. It can be used in auction house sites and person-to-person auction sites. The last one is business-to-business that involves the sales of a product of service from one business to another.Security is the greatest challenge for e-commerce development and 3 basic options are check, credit card, and digital cash.

Web Utilities are specialized utility programs that make using the Internet and the Web easier and safer.Web-based application free users from owning and storing application. The programs are accessed from a web site, copied to the user’s computer memory and run.FTP (file transfer protocol) is an Internet standard for transferring files. Downloading is the process of receiving a file from another computer. Uploading is the process of sending a file to another computer.Plug-ins is automatically loaded and operates as part of a browser. Many Web sites require specific plug-ins to fully experience their content. Filters are used by parents and organization to block certain sites and to monitor use of the Internet and the Web.Internet Security Suites is a collection of utility programs designed to protect our privacy and security on the Internet.

After finished chapter 2, on the next class we go on to the next chapter that is BASIC APPLICATION SOFTWARE.

Application software focuses on completing specific tasks or applications and there are basic application and specialized applications.Common features of most application program including Microsoft Office 2003 are user interface, windows, menus, dialog box toolbar. In 2007 Microsoft Office has some extra interface to make it easier o find and use application features such as ribbons that replace menus and toolbar, contextual tabs and galleries. some application also support speech recognition by allowing voice input. Word processors allow us to create, edit, save, and print text-based documents. Examples of word processors are Microsoft Word, Corel WordPerfect and Lotus Word Pro. Features in the word processors are word wrap and editing which include Thesaurus, Find and replace, Spelling and grammar checkers. Formatting features include Font, character effects and bulleted and numbered lists.Spreadsheet programs organize, analyzed, and graph numeric data. Examples of spreadsheet programs are Microsoft Excel, Corel Quattro Pro and Lotus 1-2-3. Features that includes in this programs are workbook files, worksheet, cells, text entries (labels), formulas, range, analytical graphs, recalculation and what-if analysis.A database is a collection of related data. Database management systems (DBMS), also known as database manager, structures a database and provides tools for entering, editing and retrieving data. Examples of DBMS are Microsoft Access, Corel Paradox and Lotus Approach. Principal database management system features include the relational database, tables, sort, query, forms and reports.Presentation graphics are programs that combine a variety of visual objects to create attractive, visually interesting presentations. Examples of presentation graphics programs are Microsoft Power Point, Corel Presentation and Lotus Freelance Graphics. Features in the principal of these programs are slides, auto content wizard, design templates and master slides. An integrated package is a single program that provides the functionality of a word processor, spreadsheet, database manager and more. Some important characteristics are function less expensive, simple to use and popular with home users.

A software suite is a collection of individual application packages sold together. It is suites to productivity that is for business, personal (home), specialized and utility also.

Since early 1940s, computers have been evolve until now in 20th century. This evolution will never stop as time pass everyday.On 1940s a digital electronic computer was made consist of 300 vacuum tubes to store information. Then from 300 tubes 5000 tubes were used and then 18000 tubes for not only stored program but also list of instruction to excute.

At first,there were only mainframe computers. It was actually a computer system cabinet that housed its central processor and main memory. This type of computer had the central processor and main memory were housed together as to increase the processing speeds and improving reliability.

Then, supercomputer was born. This type of computer is the most powerful computer of any time also the most high-speed, high perfomance, high-end computer and most recent.It is a large computer or collection of computers that act as one large computer capable of processing enormous amounts of data. Supercomputers are used for very complex jobs such as nuclear research or collecting and calculating weather patterns.

In 1960s minicomputer was invented to replaced large expensive mainframe. It was much smaller digital computers whose price and functionality were suitable to meet the need of smaller application. It was used in biomedical control for experiment monitoring and also were used industrial applications.

Microcomputer was made on 1970s then which is more complete system containing not only the CPU logic, but also memory for storing program and data with input/output interfaces for exchanging data with peripheral devices.The earliest model was came in as little 256 bytes of RAM without input/output devices. On 1979, many companies produced a system designed either for a resourceful end user or consulting firm to deliver business systems such as accounting, database management, and word processing to small businesses.As the power of the desktop computer for personal use increase, it has attracted many software developers. As microcomputer have been upgrade, many machines were invented such as modern desktop computers, video games console, laptop computers, tablet PC and many types of handheld devices, including phones and pocket calculators, as well as industrial embedded system.

Internet is the most recent technology that almost people around the world have been used.It is a network of computers that offer access to people and information. People that used the internet is approximately about 100 million within a few years. Internet can be used in variety of industry that made people work become easy and we can do a lot of things with computers.It is a "network of networks" that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber optic cables, wireless connections, and other technologies.

Internet was first invented by the U.S military in mid-1960s. Thay wanted to develop a a network that can survive if one of the computers on their network didn't because their network was in area that is critical when a network can be shut down by a single computer's malfunction that is of course a major vulnerabilty.Then in 1970 the Advanced Research Project Agency(part oft the Department of Defense) set up the first part of what would become the Internet.

Network can be classify by the geographic area they cover. These are 3 most common design; local area network (LAN), metropolitan area network (MAN), wide area network (WAN).

Local area networks or LANs are a computer network covering a small physical area, like a home, office, or small group of buildings, such as a school, or an airport. The key attribute of a LAN is its limited geographic scope, not the number of nodes that attached to the network.

Metropolitan area networks, or MANs, are large computer network usually spanning a city. They typically use wireless infrastructure or optical fibre connections to link their sites. MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities. MANs can also depend on communications channels of moderate-to-high data rates. MAN maybe owned and operated by a single organization.

Wide Area Networks or WANs are a computer network that covers a broad area any network whose communications links cross metropolitan, regional, or national boundaries. WAN is a wireless network that uses routers and public communication links. WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations.It reports that international circuits operating at speeds of 256 Kbps or 1 Mbps provide a 3 second response time to users at workstations anywhere in the world.

Question that anyone may could not answer..Who actually own or run the INTERNET??

The answer are1. Nobody2. Lots of people

Every computer that is connected to the internet is responsible for its own part of the Internet.
